访问如何在表单上显示表的记录计数

Question

I want to show a variable value (record count of a table) on an Access form. I tried with a textbox by defining its control source with the following and many other internal functions but all returned only errors. Anyone can help? Thanks

select count(*) from TableName

Answer 1

You need = and domain functions.

=DCount("*", "TableName")

should work as control source.

Answer 2

I would also suggest the DCount domain aggregate function as suggested by Andre, but to offer an alternative, if TableName is the Record Source for your form, you can also use:

=Count(*)

To count all records in the Record Source, or:

=Count([FieldName])

To count all non-null values of a particular field in the Record Source.
